Criminals are smuggling an estimated $30 billion in U.S. currency into Mexico each year from the United States, but help could be on the way for border guards, researchers will report here today. The answer to the problem: a portable device that identifies specific vapors given off by U.S. paper money. They will present the new research at the 248th National Meeting & Exposition of the American Chemical Society (ACS).
